Why a magnesium ion has a charge of 2+?
Magnesium has two electrons in its outer shell as it is in group 2 of the periodic table, which it loses, so its outer shell is full (2,8) and it has a charge of +2, as it still has 12 protons (positive charges) and now has only 10 electrons (negative charges).
Is Mg a +2 ion?
Magnesium(2+) is a magnesium cation, a divalent metal cation and a monoatomic dication.
Does Mg have a +2 charge?
Because the outer electron shell of a magnesium atom has two electrons in it. Both are lost when it changes to an ion leaving it with 12 positively charged protons and 10 negatively charged electrons. This produces a +2 positive charge.
What is the ion form of Mg?
Magnesium ions (Mg2+) are often used in protein/nucleic acid cocrystallization.

What is an ion charge?
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
